Clean up a git repo

git-cleanup.sh

#!/usr/bin/env bash

# This script will clean up your git repo by doing the following:
# => Pull the latest master
# => Perform a 'git remote prune origin'
# => Delete all local branches that are fully merged into master
# => Delete all remote branches that are fully merged into master (if the --remote option is passed)

# This has to be run from master
git checkout master

read -p "Pull master (y/n)? "
if [ "$REPLY" == "y" ]
then
   # Pull the latest master
   git pull origin master
fi

# Update our list of remotes
git fetch
git remote prune origin

# Remove local fully merged branches
git branch --merged master | grep -v 'master$' | xargs git branch -d

if [ "$1" == "--remote" ]
then
  # Show remote fully merged branches
  echo "The following remote branches are fully merged and will be removed:"
  git branch -r --merged master | sed 's/ *origin\///' | grep -v 'master$'

  read -p "Continue (y/n)? "
  if [ "$REPLY" == "y" ]
  then
     # Remove remote fully merged branches
     git branch -r --merged master | sed 's/ *origin\///' | grep -v 'master$' | xargs -I% git push origin :%
     echo "Done!"
     say "Obsolete branches are removed"
